LUBRIGATOR.

-LUBRICATOR SPECIFICATION forming part of Letters Patent No. 301,010,dated June 2%, 1884:.

Application filed April lil, 1884.

To @ZZ whom, it may concern..-

Be it known that l, PHiLLir L. SCHMITT, of Quincy, in the county ofAdams and State of Illinois, have invented a new and useful Improvementin Lubricators; and I do hereby declare that the following is a full,clear, and eX- act description of the same.

My invention relates to lubricators for steamengines of that class inwhich the oil is displaced by the condensation of steam from the boiler.

It consists in details of after explained.

The objectief the said improvements is to simplify and improve theconstruction, as hereinafter explained.

In the accompanying drawings, Figure 1 shows a vertical section of theapparatus. Figs. 2 and 3 represent modifications of the induction-pipeleading steam to the reservoir ofthe lubricator. Fig. 4t is a plan ofthe lower end of the upper iitting, and representing also the upper endof the lower fitting.

, My invention requires an upper oil-cu p, which may be of metal, fromwhich the oil is discharged by displacement, and a lower transparentchamber, through which the oil is dropped as it is displaced, and thepassage of it is noted through the glass walls ofthe chamber.

In Fig. l, E represents the upper reservoir or cup. It is provided witha hole and plug, F, through which oil may be introduced. At the lowerend it has a boss or thickened part screw-threaded for the connectionwith the part A. Atube, M, rises from the channel in the part or fittingA into the interior ot' the reservoir to a point near its top. A branch,J, of the main steampipc I has an extension, L, within the reservoirwith a stealntight Iit ting, the said extension terminating near thebottom of the reservoir. A faucet, Y, is provided for drawing oit thewater from the reservoir. The fitting A is of the form shown in thefigure. It has an upper screwplug, T, a

construction hereinthreaded projection, p, for the valvel?, and a boss,g, for the live-steam pipe G, and the valve P shuts against a seat,through which is a communicating passage leading from the pipe M to thenipple N. The lower part of the iit- (No model.)

ting is formed with an annular groove, S, around the nipple, and is in asuitable shape to serve as the top of the lower bottom', Outside oftheannular grooves are ears R, as shown in Fig. 4, for connection of thebolts D. The y Q, by means of which the passage is closed p from thelower chamber to the threaded eX- tension U. The threaded extension IIis adapted to be screwed into the steam-pipe on the line with the end Xof the pipe I, the nipple.

V projecting into the pipe. The pipe I is provided with a valve, t', forthe purpose of controlling the ilow ofsteam. The pipeJ isjoined to thepipeI by a three-way connection, H, by means ot' which the pipe G ismade to connect with the upper tting, A, by communication with apassage, a, in said tting, which pas sage leads intothe lower chamber.

It will be understood that the pipe J is in its upper part a condensing-pipeg but the `pipe Gr being shorter, a communication by more directpassage to the interior of the chamber is a live-steam pipe that conveysthe live steam into said chamber.

Ihe lubricator is lied in the ordinary manner through the upper part byremoving the plug F. By opening the valve i the steam is admittedthrough the pipe J into L, and, condensing, displaces the oil and ilowsit into the tube M. The valves IJ and Q being open, a proper amount ofoil passes through the lower chamber, in which it can be seen as itdrops from the nipple. pipe G will prevent the oil from banking up inthe glass chamber, and will force the oil through the valve in thesteam-pipe. Vhen the oil is all fed out, it may be supplied in tlhemanner above explained. Instead of the pipe .I being made as in Fig. l,I may form this tube as in the modified Fig. Q, or as in Fig. 3, wherebyThe live steani from the IOO tenson, p, for the valve, and one for thepipe G, and a lowerpart formed with grooves S, and I 5 the ears R,whereby it is adapted to form the top of the lower chamber,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two sub- 2o scribing witnesses.
